Jones, Kansas City, M0,, assignor to l' licholl Brothers, Inc, Kansas City, M0,, a corporation of Missouri Filed Jan. 29, 1962, Ser. No. 169,291 7 Claims. (Cl. 340-321) This invention relates to a lamp to be used by sportsmen, automobile owners and the like, and more particularly relates to a battery-powered lamp to serve as a source of illumination and also a signal light.

Sportsmens lamps or lanterns heretofore used have housings assembled from a plurality of parts whereby the structure is not watertight and, when dropped in Water or otherwise exposed to water, the housings leak, resulting in the lamp being rendered inoperative by shorting the electric circuit. Attempts to seal such housings have resulted in expensive gasketing and high cost structures.

The principal objects of the present invention are to provide a lamp with a one-piece housing with an open end in which is mounted in sealing engagement a bezel carrying a lens and reflector assembly to form a substantially water-tight structure; to provide such a structure wherein the housing or body is translucent to permit light radiating from within to be visible in a wide range of directions when the lamp is actuated so as to provide a warning or a distress signal in the event of an emergency; to provide such a structure wherein the body has a chamber for receiving a battery at one end thereof with a retainer for holding the battery in position and form an air space at the other end adjacent the reflector to form a buoyant structure that permits the lamp to float in water so that the same may serve as a distress signal at night should the user thereof be accidentally thrown into the water; to provide such .a structure wherein one light bulb is positioned between the reflector and lens and another light bulb is contained in the housing with said other light bulb having a blinker light mean-s so that the blinking action of said means will cause the blinker light to illuminate the translucent body and be visible over relatively great distances; to provide such .a structure which is substantially waterproof by virtue of an integral body coupled to a retainer member for interconnecting a reflector and bulb unit to the body under peripheral pressure whereby moisture is prevented form entering the joint into the body; to provide such a structure wherein a handle is molded integrally with the body; to provide such a structure with an electrically-conducting switch means therein with an enclosed actuator and a transversely poygonal hollow body for receiving therein a self-contained source of electric power whereby the lamp may be actuated by the aforementioned switch means; to provide such a structure with a bulb and reflector unit including a concave reflecting surface having a tubular bulb-receiving means secured thereto so that the bulb is easily replaced should the same become inoperative; and to provide a battery-powered lamp that is economical to manufacture, sturdy and efiicient in use and capable of floating in water.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this invention.

Referring more in detail to the drawings:

The numeral 1 designates a battery-powered lamp which generally comprises a hollow body 2, a lens, reflector and bulb assembly 3, a self-contained source of electrical power such as a battery 4, a blinker light assembly 5 and a switch means 6 adapted to electrically interconnect the bulb 7 of the assembly 3 and the blinker light assembly 5 with the source 4.

The body 2 has a portion 8 polygonal in cross-section with an end wall 9 closing one end of rear thereof, said end wall 9 being integral with side walls 10 of the portion 8. An outwardly extending wall 11 is integral with the side walls 10 and at the end thereof opposite the rear end wall 9, said outwardly extending wall 11 terminating in an annular wall '12 which extends forwardly and terminates in an outwardly and forwardly inclined portion 13 that interconnects the wall 12 with an annular forwardly extending wall portion 14 of a diameter slightly greater than the diameter of the wall 12, the wall 14 defining a forward opening for access into the interior of the body. A handle 16 is preferably for-med integrally with one of the side walls 10 of portion 8 and extends outwardly therefrom. In the embodiment shown in the drawings, the rear end wall 9, side Walls 10, outwardly extending wall 11, annular wall 12, wall portions 13 and 14 and the handle 16 are integral to form a unitary body, it being clear that the same may be molded in a single process from a lightweight material which is waterproof, yielda-ble and translucent, which also may be of desired colors, as for example red. A material which is suitable for the construction of the body and handle is polypropylene which resists impacts, has some resiliency and has all of the aforementioned characteristics. The handle is preferably molded in the same process of molding of the body to form a single unit of rugged construction. Also, the material forming the body 2 and handle 16 is substantially impervious to rust, fungus, acid, grease or the like so that the lamp 1 may be success-fully used in and around regions subjected to such noxious elements.

In the illustrated structure, the battery 4 is of a conventional type and is provided with spaced terminals 17 and 18 and is receivable in the chamber 19 defined by the side walls 10 and rear wall 9, said battery preferably being received in the chamber 19 so that the bottom or end opposite the terminals is in abutment with the rear wall 9. It is preferred that the side walls 10 be longer than the battery and, to hold the battery in place, a retainer 20 is arranged in the forward end of the chamber 19 and is secured to the body. In the structure illustrated, the retaining device is also preferably molded of suitable material such as polypropylene and is provided with a base or transverse wall 21 with integral forwardly extending side walls 22 to form an open box-like structure of suitable size whereby it is movable into and out of the chamber 19 and is adapted to have the base 21 sub stantially engage the terminal end of the battery. The base is preferably provided with upstanding hollow bosses 23 and 24 defining sockets 25 for receiving the terminals 17 and 18 respectively of the battery, said bosses having conductor terminals 26 and 27 connected therewith by suitable fastening devices such as rivets 28 which extend through the bosses and are engaged by the terminals 17 and 18 to make electrical connection. In the structure illustrated, the battery has spring type terminals which cooperate with the sockets in the bosses of the retainer to aid in holding the battery in position in the body. The side walls 22 of the retainer preferably terminate substantially flush with the forward face 29 of the wall 11 and opposed side walls of the retainer have outwardly extending flanges 30 having apertures 31 adapted to pass over heads 32 of fastening lugs suitably secured to the body whereby the heads are spaced from the surface 29 of the wall 11 and are adapted to be engaged by latch members 33 pivotally mounted on pins 34 on the flanges 36 of the retainer. In the structure illustrated, the heads 32 are on threaded shanks 32' each screwed into a threaded bore 35 of bosses 36 that extend rearwardly of the wall 11 on opposite sides of the body portion 8, the bores 35 terminating short of the rear end of the bosses whereby there is no through aperture. The latch members 33 are preferably of thin material and have notches 37 in the edge toward the heads 32, said notches being of suitable size to receive the diameter of the shanks 32' therein but of lesser size than the heads 32 whereby, when said latch members are swung to a position to embrace the shanks 32, the forward faces 38 of the latch members engage the heads 32 and the rear of the flanges 3t) engage the face 29 of the wall 11 to hold the retainer in position. The latch members each preferably have an upstanding tab 39 to facilitate swinging movement on the pivotal connection or pin 34.

The bulb, reflector and lens unit 3 includes the bulb 7, a reflector 40 having a parabolic reflecting surface 41 and a lens 42. The lens is of suitable transparent mat rial and is suitably and hermetically sealed to the forward portion of the reflector to form a substantially unitary structure having an annular or rim portion 43 with a substantially cylindrical periphery 44 for a purpose later described. The reflector 40 is provided with a rearwardly extending sleeve 45 integral therewith at the rear center and defining a central circular opening 46 coaxial to the reflector 40. The sleeve 45 receives therein a tube 47 which extends therethrough so that the forward end 48 of the tube is positioned within the space 49 between the reflector 40 and lens 42. The forward end 48 of the tube is preferably flared inwardly to form a flange 50 forming a stop means which is engaged by a flange 51 on the base 52 of the bulb 7, so that the filament of the bulb '7 is positioned substantially at the focal point of the reflecting surface 41. The flange 51 and tube 47 are of suitable electrical-conducting material so as to make an electrical connection between the tube 47 and bulb base flange 51 when the bulb 7 is in operative position, as illustrated in FIG. 3. The tube 47 is preferably suitably secured in the sleeve 45 as by adhesive or the like with the rear end portion 53 extending from the sleeve and having therein a bayonet slot 54 adapted to receive a lug 55 of a spring terminal member 56 which includes a plug-like member slidable in the bore 57 of the tube and formed of non-conducting material. The plug has a bore 58 through which a conductor 59 extends, said conductor having a terminal 60 adapted to engage a center terminal 61 on the bulb base. The terminal 60 is urged into engagement with the terminal 61 of the bulb base by means of a spring 62 having one end engaging the terminal 66 and the other end positioned in a counterbore 63 in the plug, as illustrated in FIG. 3. The tube 47 is also connected by a conductor 64 to the switch 6, as later described.

The reflector lens assembly is preferably arranged in a mounting ring or bezel 65 which has a substantially cylindrical portion 66 with an inner surface 67 having a diameter slightly less than the outer diameter of the periphery 44 of the rim portion 43 of the reflector, said cylindrical portion 66 having an outer diameter 68 substantially corresponding to the static or normal diameter of the inner surface 69 of the wall 14 of the body. The cylindrical portion 66 has an annular inturned flange 70 adapted to be engaged by the rear face 71 of the annular rim member 43 of the reflector when assembled. The bezel 65 has d an enlarged portion at the forward end thereof forming a shoulder 72 adapted to engage the forward edge 73 of the body wall portion 14. The inner surface of the forward portion of the bezel is preferably enlarged by steps as at 74 to give a tapered, progressively larger bore forwardly of the reflector lens assembly.

In assembling the reflector, lens and bulb assembly in the bezel, it is inserted with the reflector end foremost into the bezel 65 and pressed therein until the face 71 engages the flange 70. The diameter of the periphery 44 of the reflector rim 43 being larger than the diameter of the surface 67, results in the reflector rim having a pressure engagement with the surface 67 of the bezel and also swells the cylindrical portion 66 outwardly, increasing its outer diameter to a diameter greater than the diameter of the surface 69. Then, when the bezel and reflector lens assembly are inserted into the forward end of the body, pressure is required with the bezel swelling the wall portion 14 outwardly so there is a compressive fit between the bezel and the body and between the bezel and lens reflector assembly, providing a continuous pressurized engagement forming a positive seal, and, when assembled as illustrated in FIG. 3, there is substantial air space between the reflector and the forward end of the battery 4. Under extremely adverse moisture conditions such as encountered during skin-diving and the like when the lantern may be completely submerged under sev eral feet of water, additional sealing members may be desirable. In the illustrated example, a band 65' of elastic material such as neoprene, rubber or synthetic resin with similar properties is maintained in stretched condition covering the line of juncture formed between the mutually engaging shoulder 72 and forward edge 73. A suitable base clamp 66 is preferably of stainless steel and comprises a band portion 67 having perforated slots 68' adjacent one end thereof adapted to engage threads (not shown) of a screw 69 rotatably mounted in a housing '70 secured to the other end of said band portion. The band portion 67 in the illustrated structure is substantially the same width as the band 65 and is, placed circumferentially thereover and tightened by rotating the screw 69, urging the band 65 into tight sealing contact against the lantern surface.

The blinker light 5 may be suitably mounted as desired; however, in the illustrated structure, it is arranged in a socket 75 carried by a bracket 76 mounted on the boss 24 and in electrical engagement with the terminal end 27 of a conductor 77 that leads to the switch 6. The socket 75 is provided with a conductor connection 78 which conductor also leads to the switch 6. The blinker bulb 5 is preferably of such a structure wherein it has a heat-responsive element 79 located adjacent a filament post 80 whereby the element 79 is operative when the bulb is energized to make and break the circuit to the filament.

The switch assembly 6 in the illustrated structure has a threaded shank 81 which extends through an opening 82 in the wall 12 with nuts 83 and 8.4 on said threaded shank respectively urged toward the inner and outer surface of the wall 12 to secure the switch assembly in place. The switch assembly has a pushbutton member 85 which is covered by a flexible cap member 86 which extends in surrounding relation to the nut 84 with a rib 87 on said nut engaged in a groove 88 to aid in providing a seal, the rib and groove being located whereby the portion of the cap between the rib and the wall 12 is compressed to form a seal therearound. An annular disc or washer 88' preferably of soft rubber, neoprene or the like has an inside diameter substantially equal to the outside diameter of the threaded shank 81 and an outside diameter at least equal to the outside diameter of the cap member 86. The washer 88 is cemented to the nut 84 and the cap member 86 and cooperates therewith to produce a positive seal about the opening 82 when urged against the body 2 by rotating the nut 84 on the threaded shank 81. It is noted that, when desired, air may be conveniently bled through the opening 82 by backing off the nut 84 a few turns. This is important during the assembly or removal of the bezel 65 from the lantern body. With this structure, the cap member 86 is flexed when the user of the lamp presses inwardly thereon to actuate the switch.

Electrically-conducting wires 89 and '77 lead from the couductor terminals 26 and 27 respectively connecting the battery terminals 17* and 18 to the switch and conductors 59 and 64 lead from the switch to the connections to the bulb 7 and the conductor 77 leads from the switch to the blinker light 5, and the switch is preferably a multlple position type wherein switch contacts are progressively moved from one position to another in response to actuation of the pushbutton member 85, with the first position being olf, the second position completing the circuit energizing the bulb 7, the third position energizing both the bulb 7 and the blinker bulb 5, and the fourth position energizing the blinker bulb 5 alone, the next position being back to the 01f position. With this arrangement; energization of the bulb 7 provides an illuminating light or beam and energization of the bulb 5 provides a blinking light and, by virtue of the translucency of the body 2, the blinking light illuminates the body and is visible for great distances to convey the impression of an emergency or other attention-attracting signal.

When it is desired to replace a battery, the bezel 65 is grasped and pulled from the body, the reflector, lens and bulb assembly 3 being carried by the bezel. The latches 33 are then released whereby the retainer 20 is moved outwardly of the body, and then the battery 4 may be taken from the chamber 19. A new battery is positioned in the chamber 19, the retainer 20 moved whereby the terminals of the battery are located in the sockets of the bosses 23 and 24, the latches 33 are engaged with the heads 32 of the fastening lugs to hold the battery in place, and then the bezel assembly is pressed back into the forward end of the body in a tight fit with the interior of the wall portion 14 again providing a watertight seal. The lamp is then ready for operation.

In operation, the user of the lamp 1 grasps the handle 16 to carry the structure, and he can operate the switch member 85 by the fingers of the hand grasping the handle 16. In one application of the lamp, as illustrated in FIG. 1, with an automobile 90, the light structure may be placed on the ground with the lens toward the wheel 91 whereby the light beam from the bulb 7 will provide illumination for changing the wheel. Due to the construction of the body 2, the longitudinal axis of the beam of the lamp is directed slightly upwardly when the lamp is disposed on a flat surface such as the ground. Thus, the field of illumination is from the ground upwardly so that considerably more of the illumination is utilized. If

desired, the blinker light 5 can be energized simultaneously with the bulb 7 .to provide both the blinking signal and the illumination. The lamp 2 may also be placed on a flat surface to rest on the rear wall 9 whereby the beam is directed upwardly. If the lamp structure should be dropped in water, the battery is the heaviest portion due to the lightweight materials in the'remaining structure; therefore, the rear end portion of the body will be the lowest point with the lamp substantially vertically disposed. The lightweight materials of the body and other structure, in addition to the relatively large volume of water displaced by the lamp when positioned in water, provides a buoyant strfict-ure that will float with the lens upwardly and out of the water, the lamp being capable of floating and remaining buoyant as the structure is substantially waterproof. The lamp 1 is of rugged construction to the extent that it will not be damaged should it be dropped from a height above the ground. As the battery is'retained in position, the lens reflector unit is effectively seated within the body, any damage is highly improbable, and the lamp is thereby versatile and applicable to a variety of uses.
